+/**

+ *
+ * ACE: The cache is a double-sided space of ACE_Timeprobe objects. For example if there is 10 probes there
+ * will be a two lists of 10 probes all initialized. When a record is made, the appropriate probe is found,
+ * add the measurement is made.
+ *
+ * TAO: The cache is still double sided but this time the X argument is a handle_t. The appropriate monitor
+ *      map is located in the Metrics_Cache, find the data, and if there is nothing wrong with the data
+ *      make a time measurement. The data is actually a ACE_Metrics_Timeprobe (Why not TAO_Metrics_Timeprobe?)
